President Donald Trump left himself open for both mockery and criticism after he tweeted, "They are laughing their asses off in Moscow," at American discord following the 2016 election.

The president went on two Twitter binges on Sunday morning -- one calling on the Justice Department to investigate former President Barack Obama -- and another about Russia.

“If it was the GOAL of Russia to create discord, disruption and chaos within the U.S. then, with all of the Committee Hearings, Investigations and Party hatred, they have succeeded beyond their wildest dreams,” he wrote. “They are laughing their asses off in Moscow. Get smart America!”

That tweet opened the floodgates on Twitter. see below:
